You're paying for 500 Mbps but speed tests consistently show 150 Mbps. Your ISP advertises "blazing fast" internet but your video calls drop and streaming buffers constantly. This isn't just frustrating — it may be a violation of your service agreement and FCC guidelines.
ISPs collect billions in monthly fees for speeds they don't always deliver. Here's how to document the problem, get bill credits, and force your provider to fix the issue or reduce your bill.
How to Properly Test Your Speed
Do This Right (Common Mistakes Invalidate Results)
- Use ethernet, not WiFi — WiFi adds variables that aren't your ISP's fault
- Test at multiple times — morning, afternoon, evening, weekend
- Close all other applications using bandwidth
- Disconnect other devices from the network during tests
- Test over several days — one bad test isn't a pattern
Recommended Testing Tools:
- FCC Speed Test (speed.measurementlab.net) — most credible for regulatory complaints
- Speedtest by Ookla (speedtest.net) — widely recognized
- Fast.com — Netflix's tool, good for streaming-relevant speeds
- Your ISP's own speed test — useful because they can't dispute their own results
What to Record:
- Date and time of each test
- Download speed (Mbps)
- Upload speed (Mbps)
- Latency/ping (ms)
- Your plan's advertised speed for comparison
- Screenshot each result
What Speeds You Should Actually Be Getting
ISP Advertising Standards:
- "Up to" language: ISPs advertise maximum possible speeds, not guaranteed
- FCC guidance: Speeds should be achievable during "normal use periods"
- Industry standard: Most ISPs internally define acceptable as 80%+ of advertised during non-peak
- Your threshold for complaint: Consistently below 70% of advertised speed is strong grounds
Acceptable vs. Unacceptable Performance:
| Plan Speed | Acceptable Range | Complaint Threshold |
|---|---|---|
| 100 Mbps | 80-100 Mbps | Below 70 Mbps consistently |
| 300 Mbps | 240-300 Mbps | Below 210 Mbps consistently |
| 500 Mbps | 400-500 Mbps | Below 350 Mbps consistently |
| 1 Gbps | 800-1000 Mbps | Below 700 Mbps consistently |
Step-by-Step: Getting Credits and Fixes
Step 1: Document for 7-14 Days
Run speed tests 3x daily (morning, afternoon, evening) via ethernet for at least a week. Create a log with timestamps and results.
Step 2: Call Your ISP With Data
"I'm calling about consistent underperformance on my internet service. I'm paying for [X] Mbps but my speed tests over the past two weeks show I'm consistently getting [Y] Mbps — about [Z]% of what I'm paying for. I have [14] documented speed tests showing this pattern. I'd like either a credit for the service not being delivered or a resolution to bring speeds up to what I'm paying for."
Step 3: Request Specific Remedies
- Bill credit for months of underperformance
- Technician visit to check your line/equipment (at no charge — it's their service failing)
- Equipment upgrade if your modem/router is outdated
- Plan adjustment to match what they're actually delivering (at lower price)
Step 4: File an FCC Complaint (If ISP Doesn't Resolve)
Go to consumercomplaints.fcc.gov:
- Select "Internet" category
- Describe the issue with specific speed data
- Attach speed test screenshots
- ISP must respond within 30 days
Step 5: Consider Alternatives
If your ISP can't deliver advertised speeds:
- Check if a competing ISP serves your address (fiber often delivers more consistent speeds)
- Fixed wireless (T-Mobile Home Internet, Verizon Home) may perform better
- File with state public utilities commission if ISP is a local monopoly
Common ISP Responses (and Your Counter)
"WiFi speeds aren't guaranteed"
Counter: "I tested via ethernet directly connected to the modem. WiFi isn't a factor."
"Speeds are 'up to' — not guaranteed"
Counter: "Consistent performance at 40-50% of advertised isn't 'up to' — it's systematic underdelivery. The FCC expects speeds achievable during normal use."
"It's a congestion issue during peak hours"
Counter: "My tests show underperformance at all hours, including off-peak. Regardless, I'm paying for service that should work during the hours I use it."
"Your equipment might be the issue"
Counter: "I'm using [ISP-provided or ISP-approved] equipment. If it can't deliver the speeds I'm paying for, please provide equipment that can."
Quick Checklist
- [ ] Tested speeds via ethernet (not WiFi) over 7-14 days
- [ ] Documented all results with timestamps and screenshots
- [ ] Calculated average speed vs. advertised plan speed
- [ ] Called ISP with specific data requesting credits/resolution
- [ ] Requested technician visit at no charge
- [ ] Filed FCC complaint if ISP didn't resolve within 14 days
- [ ] Checked for competing ISPs serving your address
- [ ] Considered downgrading plan to match actual delivered speeds
Bottom Line
You're paying for a specific level of service — if it's consistently not delivered, you're owed credits or a fix. The combination of documented speed tests and an FCC complaint produces results the vast majority of the time. ISPs take FCC complaints seriously because patterns lead to regulatory enforcement, and most will offer bill credits or send technicians rather than accumulate complaint records.
